摘　　要： 分析了新鲜江蓠生产琼胶的残渣的成分构成,采用正交试验实验法,筛选出了残渣提取膳食纤维漂白的较佳工艺条件。结果表明,在本实验条件下得到的膳食纤维的膨胀力为5.1mL/g,持水力为490.74%,白度为38.9%,质量和功能性指标远超过西方国家麸皮膳食纤维的标准(膳食纤维干基质量分数47%、膨胀力4mL/g、持水力400%);高温挤压可以改善膳食纤维的物性。 The composition of residue from Agar production with Gracilari were analysed. The optimum technological conditions for bleaching of dietary fiber had been selected by orthogonal design method. The results showed that the expansion capacity, water holding capacity and whiteness were 5.1 mL/g, 490.74 % and 38.9 % respectively. The functional property exceeded the standard of the western nations. The functional property can be modified with the treatment of extrusion under high temperature.
